DOOR FOR COKE-OVENS.

SPECIFICATION forming part of Letters Patent No. 578,510, dated March 9,1897.

Application filed July 22,1896. Serial No. 600,124. (No model.)

To all whom t may concern:

Be it known that I, CHARLES W'ILSON GAR- LAND, a citizen of the UnitedStates, residing at McDowell, in the county of McDowell and State ofWest Virginia, have invented' a new and useful Door for Coke-Ovens, ofwhich the following is a specification.

The invention relates to improvements in doors for coke-ovens. f

The object of the present invention is to improve the construction ofcoke-oven doors, and to provide a simple, inexpensive, and efficient onewhich will enable a coke-oven to be quicklyopened and closed to avoidkeeping an oven open any great length of time, whereby loss of heat isavoided and an oven may be maintained at the proper temperature.'

A further object of the invention is to provide an oven-door in whichthe metal parts will not be directly exposed to the heat of an oven,whereby the expansion and contraction of the metal are prevented .andconsequent warping and cracking avoided.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated l in theaccompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure l isa Yfront elevation of a coke-ovenconstructed in accordance with this invention. Fig. 2 isa verticalsectional view on line 2 2 of Fig. 1. Fig. 3 is a horizontal sectionalview on line 3 3 of Fig. 1. Fig. 4 is a detail sectional view on line 4@of Fig. 1. Fig. 5 is a detail view of the nre-brick lining of one ofthe lower doors. Fig. 6 is a similar view of one of the lower doors, thelining being removed.

Like numerals of reference designate correspondin g parts in all thefigures of the drawings.

1 designates a coke-oven door comprising a pair of upper doors 2 and 3and a pair of lower doors 4 and l5, all of the doors being provided attheir outer side edges with projecting eyes 6, arranged on verticalpintlerods 7, whereby the doors are hinged to an The vertical pintle-rods are supported being provided with inclined braces 10, locatedndirectly beneath and supporting the pintle-rods. The lower terminals ofthe inclined braces 10 are bent outward to form feet, which aresupported upon the ledge located at the base of the oven. The upperdoors are supported by collars 7, mounted on the pintle-rods and locatedbeneath the lower eyes of the upper doors to relieve the lower doors ofthe weight of the upper ones, and these collars are provided withclamping-screws to enable them to be secured at the proper adjustment.

The doors 2, 3, 4, and 5 are provided, respectively, with fire-bricklinings 11, 12, 13, and 14, and each door, which is constructed ofmetal, has at its inner face vert-ical rods 15, located at the sideedges and at the centers of the doors and fitting in ycorrespondinggrooves 16 and 17 of the linings, whereby the latter are mounted on thedoors. The ribs 15, which are beveled at their side edges, arewedge-shaped in crosssection, and the grooves 16 and 17 of the liningsare correspondingly beveled, whereby the linings are interlocked withthe doors. The lower ends of the vertical ribs are connected by ahorizontal rib 18, beveled at its upper edge and fitting in acorresponding horizontal groove i 19 of the lining.

The upper terminals of the vertical'ribs are inwardly beveled orinclined, and the upper ends of the grooves 16 and 17 arecorrespondingly shaped, and the linings, which are interlocked with thedoors by sliding downward on the inner face thereof to engage the saidribs, are locked against upward movement by horizontal pins 20, locatednear the upper edges of the doors and fitting in registeringpertorations of the doors and the linings.

The vertical ribs of the doors are of greater thickness than the depthof the grooves of the linings, whereby the latter are inwardly offsetfrom the doors to provide an intervening air-space 21, and the doors areprovided at intervals with perforations 22, communieating with theair-spaces 21 and with the outside atmosphere, and permit any heatcollecting in the air-space to escape.

The inner edges of the linings of the upper and lower doors are beveledand overlap to provide a tight joint, as clearly illustrated in IOOFigs. 3 and4 of the accompanying drawings, and the adjacent horizontaledges of the linings of the doors are beveled and overlap, asillustrated in Fig. 2 of the accompanying drawings, whereby when theupper and lower doors are closed the linings will form a solid and theseopenings afford access to the integ rior of the oven and permit theoperator to lire up the same and maintain the oven at the propertemperature. The overlapping flanges 27 for closing the joints at theadjacent edges of the doors are provided and are located vat the innerand bottom edges of the door 3, at the 'lower edge of the door 2, and atthe inner edge of the door 5, as shown, and these flanges are recessedadjacent tothe openings 23 and 24. The inner abutting edges of the upperand lower doors and their linings are oppositely beveled, as clearlyillustrated in Figs. 3 and 4 of the accompanying drawings, andreversely-arranged, hasps 28 and 29 are provided for securing the doorswhen closed. The hasps are provided at their outer ends with openingsfor the reception of staples, to which they are secured by any suitablefastening devices, and the doors are provided with suitable handles.

It will be seen that the coke-oven door is simple and comparativelyinexpensive in construction, that it will enable coke-ovens tobe rapidly opened and closed in order to prevent loss of heat, and thatthe metal of the door is protected by a solid wall of fire-brick and isprevented from warping and cracking.

It will also beapparent that any heat collecting in the interveningspace between the linings and the doors is permitted to escape throughthe openings or perforations 22.

An oven-door comprising the upper and lower pairs oi' doors hinged attheir outer edges and provided with perforations, the lower doors beingprovided at their upper and lower edges with openings 23 and 24, and theremovable linings detachably interlocked with the doors, formingintervening spaces between them and the doors and provided with openingscorresponding with the openings 23 and 24, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

CHARLES WILSON GARLAND.
